Flawless Herend Frog King and Queen. I am offering for auction the beautiful Flawless Herend Frog King and Queen porcelain shown in the pictures. The statue is rare and in good condition. Since its foundation in 1826, the Herend Porcelain Manufactory has been faithfully producing its handcrafted masterpieces. Porcelain used to be called "white gold", it was a privilege to own it, it meant status, it was a desired object, it was valuable.
